Abstract (en)

[origin: EP1927951A2] An image adjustment amount determination device comprises: processing target image determination means for receiving an input video signal which comprises a plurality of frame images and which is input from the outside, for dividing the input video signal into the plurality of frame images, and for determining a processing target image which is to be the target of image processing and one or more neighboring images which are located in the vicinity of the processing target image in the display order, on the basis of a predetermined criterion from the plurality of frame images; image characteristic extraction means for extracting a feature quantity relating to the neighboring images thus determined; and image adjustment amount determination means for determining at least one adjustment amount of the amplitude and bandwidth of a spatial frequency component relating to the processing target image thus determined, on the basis of the feature quantity that relates to the neighboring images thus extracted.
